Description

The present application relates to the field of communications technologies, and in particular, to an Automatic Neighbor Relation (ANR) measurement method, apparatus, and system.
Background
Currently, for a New Radio (NR) system, most operators adopt non-independent Networking (NSA), that is, a core network of a 4th generation (4G) network is used, the 4G network is used as an anchor point of a control plane, and a dual-connection mode of a Long Term Evolution (LTE) system and an NR system is adopted, and an existing 4G network is used to deploy a 5th generation (5G) network to realize rapid deployment of the 5G network, where the access mode is called an evolved universal terrestrial radio access network (E-UTRAN) and NR dual-connection (EN-DC) networking.
The terminal may communicate with the 4G network and the 5G network in a Discontinuous Reception (DRX) mode. In the DRX mode, a terminal can receive a Physical Downlink Control Channel (PDCCH) during an active time (active time) in one DRX cycle, and the terminal enters an inactive time (also referred to as a sleep time) except for the active time, and does not receive the PDCCH during the inactive time. When the terminal is in a connected state, a DRX mode of the terminal may be referred to as a Connected Discontinuous Reception (CDRX) mode.
In the ENDC system, if a terminal needs to measure neighbor cell information of an LTE neighbor cell, under the condition that the terminal is in a connected state with an NR base station, communication of the terminal on an NR cell needs to be temporarily disconnected, and the measurement of the neighbor cell information of the NR neighbor cell is similar, so that flow interruption can be caused by the scheme.

The system chip is also called a system on chip, or SoC chip. Specifically, the communication device may be a terminal such as a smartphone, and may also be a system chip or a communication chip that can be provided in the terminal. The communication chip may include one or more of a radio frequency processing chip and a baseband processing chip. The baseband processing chip is sometimes also referred to as a modem or baseband processor or baseband module. In physical implementation, the communication chip may be integrated inside the SoC chip or may not be integrated with the SoC chip. For example, the baseband processing chip is integrated in the SoC chip, and the radio frequency processing chip is not integrated with the SoC chip. The ANR measurement method will be described below by taking a communication apparatus as an example. The ANR measurement method comprises the following steps: and the terminal establishes RRC connection with the first access network equipment and the second access network equipment respectively, and performs ANR measurement on the adjacent cells according to the frequency band combination met by the first frequency band and the at least one second frequency band.

In order to make the embodiments of the present application clearer, concepts and parts related to the embodiments of the present application will be briefly described below.
1. DRX mode
The DRX mode is a mode in which a terminal receives a signal, and in order to reduce power consumption of the terminal, the terminal may determine whether to receive a signal in the DRX mode according to a configuration of an access network device. When the terminal receives a signal in the DRX mode, the terminal may receive the PDCCH during an active time (active time) during one DRX cycle, and beyond the active time, the terminal may enter an inactive time (inactive time) (which may also be referred to as a sleep time) during which the terminal does not receive the PDCCH. For example, referring to fig. 2, in both DRX cycle 1 and DRX cycle 2, the terminal can only receive PDCCH during the active time. It should be noted that, in fig. 2, the active time and the inactive time in one DRX cycle are drawn as an example of a continuous time period, and in one DRX cycle, the active time may also be composed of a plurality of discontinuous time periods, and the inactive time may also be composed of a plurality of discontinuous time periods.
When the terminal is in a connected state, the DRX mode of the terminal may be referred to as CDRX mode. In the endec system, the terminal may use the same CDRX configuration or different CDRX configurations when communicating with the LTE base station and the NR base station. The CDRX configuration determines the length of the active and inactive time of the terminal.
2. Master Information Block (MIB)
The MIB may be used for downlink synchronization and may carry some cell parameters.
In the LTE system, the MIB is transmitted on a Physical Broadcast Channel (PBCH). Referring to fig. 3, the PBCH is located on the first 4 Orthogonal Frequency Division Multiplexing (OFDM) symbols of the 2 nd slot (slot) (i.e., slot 1) of subframe 0 of each system frame in the time domain, and occupies 72 central subcarriers (without dc carriers) in the frequency domain.
In NR systems, MIB is also transmitted on PBCH, which is transmitted with a period of 80 milliseconds (ms), and the specific slot position within the period is determined by synchronization signals and PBCH block (SSB) patterns (patterns).
3. System information Block 1(System information Block1, SIB1)
The SIB1 may be used to indicate the scheduling period and scheduling window of subsequent SIBs.
In an LTE system, SIB1 employs a fixed, 80ms scheduling period, which can be retransmitted within 80 ms. The first transmission of SIB1 is scheduled on subframe 5 of a system frame with a residue of 0 per System Frame Number (SFN) to 8 (i.e., SFN mod 8 ═ 0), while the retransmission is scheduled in subframe 5 of all other system frames with a residue of 0 to 2 (i.e., SFN mod 2 ═ 0) (see fig. 4). Where "mod" is a "remainder function".
In the NR system, the transmission period of the SIB1 is fixed to 160ms, and the transmission is repeated in the period, and the specific position of the repeated transmission is determined by a combination of an SSB pattern and a control resource set (CORESET).
4、ANR
In today's cellular mobile networks, one of the most time consuming tasks is the establishment and optimization of neighbour relations. The ANR function is able to automatically create and update neighbor relations between the serving cell (e.g., the MCG and SCG described above) and the neighbors to support cell handover. ANR functions can reduce the time required for configuration and planning of the network, optimizing network performance. The process of obtaining information of a neighboring cell of the serving cell through measurement may be referred to as ANR measurement.
In an ENDC system, when the signal quality of a PCell of a terminal is lower than a specified threshold, an access network device sends an RRC reconfiguration (RRC reconfiguration) message to the terminal to inform the terminal to initiate ANR measurement so as to discover a neighbor cell. The terminal automatically maintains the neighboring cell relationship in the E-UTRAN system, and the integrity, validity and correctness of the neighboring cell relationship between different systems such as a next generation radio access network (NG-RAN), an E-UTRAN, a Universal Mobile Telecommunications System (UMTS) terrestrial radio access network (UMTS terrestrial radio access network, UTRAN), a global system for mobile communications (GSM enhanced)/data rate GSM evolution (enhanced data for GSM evolution, EDGE) radio access network (GSM/EDGE radio access network, GERAN), and the like. And the terminal reports the measured neighboring cell information (e.g., Cell Group Identity (CGI)) of the neighboring cell satisfying the condition to the access network device through an air interface, so that the access network device updates the neighboring cell relationship for handover decision.
The LTE ANR measurement (namely the ANR measurement of an LTE adjacent region, the LTE adjacent region is an adjacent region with a network standard of LTE) and the NR ANR measurement (namely the ANR measurement of an NR adjacent region, the NR adjacent region is an adjacent region with a network standard of NR) both comprise an MIB of a dendriform region and an SIB1 of the dendriform region. The terminal realizes downlink synchronization with a network device to which the neighboring Cell belongs by decoding an MIB of the neighboring Cell, acquires an operator identity (MCC) or a country identity (MNC) of the neighboring Cell by decoding an SIB1 of the neighboring Cell, and then adds a physical Cell identity (Cell ID) of the neighboring Cell to form a CGI of the neighboring Cell, and reports the CGI of the neighboring Cell to an access network device for maintaining a relationship of the neighboring Cell.
ANR measurements include two modes of idle time (idle period) and autonomous gap (autonomous gap). idle period refers to an ANR measurement mode for disconnecting communication of the terminal on all serving cells to receive MIB and/or SIB1 of the neighboring cell and acquiring neighboring cell information according to the received MIB and/or SIB1 during the deactivation time of CDRX. The autonomous gap refers to a window for receiving MIB and/or SIB1 of the neighboring cell (the size of the window may be determined according to the prior art, and is not described again, and for convenience, the window is hereinafter referred to as a receive window), disconnects communication of the terminal on all serving cells to receive MIB and/or SIB1 of the neighboring cell, and obtains an ANR measurement mode of the neighboring cell information according to the received MIB and/or SIB 1.
At present, an LTE system supports two ANR measurement modes, namely, idle period and autonomous gap, and NR only supports the ANR measurement mode of idle period.
5. Radio frequency nonvolatile (Non-Volatilientem, NV)
The radio frequency NV refers to non-volatile radio frequency data. The radio frequency NV may be stored in a non-volatile memory (NVM).
The radio frequency NV includes any one or more of: logic control parameters such as sending and receiving, temperature compensation, calibration parameters, audio related parameters, Input/Output (I/O) control parameters, charging current consumption and other current control parameters. The radio frequency NV may also include other radio frequency related data.
One carrier may correspond to one radio frequency NV. The radio frequency NV can be validated by loading the radio frequency NV (i.e., loading the radio frequency NV in the NVM into memory).
6. Radio frequency front end path
The RF front-end path is between the antenna and the RF transceiver, and the components mainly include a filter (Filters), a Low Noise Amplifier (LNA), a Power Amplifier (PA), an RF switch (RF switch), an RF antenna switch (RF antenna switch), and a duplexer.
The rf front end path may also be referred to as an rf resource, an rf channel, an rf switch, an rf front end, etc., and the present application is not limited thereto.
The radio frequency front end path comprises a receiving path and a transmitting path, and the signal transmission is seen from the line:
the signal transmission of the receiving path is as follows: signal-antenna-rf tuning switch-filter/duplexer-LNA-rf switch-rf transceiving-baseband.
The signal transmission of the sending path is as follows: baseband-rf transmit-receive-rf switch-PA-filter/duplexer-rf tuning switch-antenna-signal.
The antenna is used for transmitting and receiving radio waves. The radio frequency switch is used for realizing the switching of receiving and sending of radio frequency signals and the switching between different frequency bands (bands). The LNA is used to achieve radio frequency signal amplification of the receive path. The PA is used to achieve radio frequency signal amplification of the transmit path. The filter is used for reserving signals in a specific frequency band and filtering out signals outside the specific frequency band. The duplexer is used for isolating the transmitting signal and the receiving signal, and ensures that the receiving and the transmitting can work normally under the condition of sharing the same antenna.
One carrier may correspond to one rf front-end path, and when one carrier is used to transmit data, it is necessary to ensure that the rf front-end path (receiving path and/or transmitting path) corresponding to the carrier is open. Specifically, the purpose of opening the rf front-end path can be achieved by configuring the rf NV in the corresponding device at an appropriate time.
Currently, after a terminal is configured to initiate an ANR measurement, the terminal in the prior art may adopt the following scheme 1 or scheme 2 to perform the ANR measurement.
Scheme 1
In the ENDC system, when a terminal needs to measure neighbor cell information of an LTE neighbor cell, if the terminal is in a connected state with an NR base station, the terminal informs the NR base station to temporarily disconnect the communication of the terminal on a cell in an SCG. Similarly, when the terminal needs to measure the neighbor cell information of the NR neighbor cell, if the terminal is in a connected state with the LTE base station, the terminal notifies the LTE base station to temporarily disconnect the communication of the terminal on the cell in the MCG. This scheme can cause traffic disruption.
For example, taking the neighboring cell information of the LTE neighboring cell that the terminal needs to measure, referring to fig. 5 (a rectangular frame in fig. 5 is a subframe, and a shaded portion in fig. 5 is an ANR measurement time period), a process of the terminal performing an ANR measurement in an idle period ANR measurement manner may include the following steps:
1. and the terminal enters the non-activation time of the LTE CDRX and judges that ANR measurement needs to be started.
When the terminal determines that the LTE CDRX has enough idle period for ANR measurement (that is, the length of the inactivity time of the LTE CDRX is enough for ANR measurement), the terminal determines that ANR measurement needs to be started.
2. When the terminal is in a connected state with the NR base station, the terminal notifies the NR base station to temporarily disconnect the communication of the terminal on the cell in the SCG.
3. And the terminal loads the radio frequency NV of the carrier wave of the LTE adjacent cell.
4. The terminal starts LTE ANR measurement.
5. And the terminal completes LTE ANR measurement.
Between step 4 and step 5, the terminal may perform ANR measurement, that is, receive and analyze the MIB and SIB1 of the neighboring cell, and obtain the CGI of the neighboring cell. Then, the terminal may report the CGI of the neighboring cell to the LTE base station.
6. When the terminal disconnects communication on the cell in the SCG before the NR base station, the terminal notifies the NR base station to resume communication between the terminal and the cell in the SCG.
7. The communication of the terminal and the cell in the SCG resumes.
For example, taking the neighboring cell information of the LTE neighboring cell that the terminal needs to measure, referring to fig. 6 (one rectangular frame in fig. 6 is a subframe, and a shaded portion in fig. 6 is an ANR measurement time period), a process of the terminal performing an ANR measurement by using an ANR measurement manner of an autonomous gap may include the following steps:
1. and after the terminal judges that the subframe 1 is the sending position of the MIB or SIB1 of the LTE neighboring cell in the subframe 0, the terminal decides to start ANR measurement.
2. When the terminal is in a connected state with the NR base station, the terminal notifies the NR base station to temporarily disconnect the communication of the terminal on the cell in the SCG.
3. And the terminal loads the radio frequency NV of the carrier wave of the LTE adjacent cell.
4. The terminal starts LTE ANR measurement.
5. And the terminal completes LTE ANR measurement.
6. When the terminal disconnects communication on the cell in the SCG before the NR base station, the terminal notifies the NR base station to resume communication between the terminal and the cell in the SCG.
7. The communication of the terminal and the cell in the SCG resumes.
Under the ENDC system, the LTE CDRX configuration and the NR CDRX configuration can be different, and the Physical Downlink Shared Channel (PDSCH) scheduling is completely asynchronous. It means that when the terminal enters the LTE CDRX inactivity time, it may still be at the NR CDRX active time. In scheme 1, when determining whether to start LTE ANR measurement, only LTE CDRX inactivity time is considered, and NR CDRX inactivity time is not considered, but communication between the terminal and a cell in the SCG is directly interrupted, which has a large influence on traffic. For example, referring to fig. 7, when LTE ANR measurement is not performed, the terminal uses the radio frequency front end path 1, the radio frequency front end path 2, and the radio frequency front end path 3 to communicate on the NR cell 1, the NR cell 2, and the NR cell 3, respectively, where the NR cell 1 is a main secondary cell, and the NR cell 2 and the NR cell 3 are a secondary cell 1 and a secondary cell 2, respectively. When the terminal performs LTE ANR measurement, the NR base station disconnects the terminal from communication in the NR cell 1, the NR cell 2, and the NR cell 3, and the terminal uses a radio frequency front end path (for example, the radio frequency front end path 1) to communicate with the LTE neighbor, thereby performing ANR measurement.
Scheme 2
Compared with the scheme 1, when the terminal needs to measure the neighbor information of the LTE neighbor, the scheme 2 is to start the ANR measurement after the terminal enters the LTE CDRX inactivity time and enters the NR CDRX inactivity time. That is, when the terminal enters the LTE CDRX inactivity time (ANR measurement mode for idle period), or acquires the transmission position of MIB or SIB1 of the LTE neighbor (ANR measurement mode for autonomous gap), the ANR measurement cannot be performed, and the ANR measurement is started only after the terminal enters the NR CDRX inactivity time.
Compared with the scheme 1, when the terminal needs to measure the neighbor information of the NR neighbor, the scheme 2 is to start ANR measurement after the terminal enters the NR CDRX inactivity time and enters the LTE CDRX inactivity time. That is, when the terminal enters the NR CDRX inactivity time (ANR measurement mode for idle period), ANR measurement cannot be performed yet, and the ANR measurement is started only after the terminal enters the LTE CDRX inactivity time.
Because the LTE CDRX configuration and the NR CDRX configuration may be different, and the PDSCH scheduling is completely asynchronous, compared to the case that whether the ANR measurement is started is selected only by considering the LTE CDRX configuration or the NR CDRX configuration, whether the ANR measurement is started is selected by considering the LTE CDRX configuration and the NR CDRX configuration, a window time of the ANR measurement is greatly reduced, the LTE ANR measurement or the NR ANR measurement cannot be started for a long time, the ANR measurement scheduling is delayed, the neighbor discovery is not timely, and the accuracy of switching initiated by the network side is affected.
For example, referring to fig. 8, when only LTE CDRX inactivity time or only NR CDRX inactivity time is entered, or a sending position of MIB or SIB1 of an LTE neighboring cell is acquired, the terminal does not start LTE ANR measurement, and the terminal communicates on NR cell 1, NR cell 2, and NR cell 3 by using radio frequency front end path 1, radio frequency front end path 2, and radio frequency front end path 3, respectively, where NR cell 1 is a primary and secondary cell, and NR cell 2 and NR cell 3 are secondary cell 1 and secondary cell 2, respectively. When the terminal enters the LTE CDRX inactivity time and the NR CDRX inactivity time, the terminal starts LTE ANR measurement, the NR base station disconnects the terminal from communicating in the NR cell 1, the NR cell 2, and the NR cell 3, and the terminal communicates with the LTE neighbor cell by using a radio frequency front end path (for example, the radio frequency front end path 3) to perform ANR measurement.
In order to solve the above problem, an embodiment of the present invention provides an ANR measurement method, which performs ANR measurement based on a band combination (band combination) relationship, and can reduce flow interruption and avoid ANR measurement scheduling delay. The method may be performed by a communication device, which may be a complete computer of the computing apparatus, or may be a part of a device in the computing apparatus, for example, a chip related to a wireless communication function, such as a system chip and a communication chip. The system chip is also called a system on chip, or SoC chip. Specifically, the communication device may be a terminal such as a smartphone, and may also be a system chip or a communication chip that can be provided in the terminal. The communication chip may include one or more of a radio frequency processing chip and a baseband processing chip. The baseband processing chip is sometimes also referred to as a modem or baseband processor or baseband module. In physical implementation, the communication chip may be integrated inside the SoC chip or may not be integrated with the SoC chip. For example, the baseband processing chip is integrated in the SoC chip, and the radio frequency processing chip is not integrated with the SoC chip.
The ANR measurement method will be described below by taking a communication apparatus as an example. As shown in fig. 9, the method includes:
901. and the terminal establishes RRC connection with the first access network equipment and the second access network equipment respectively.
The first access network equipment adopts a first network standard, the second access network equipment adopts a second network standard, and the first network standard and the second network standard are different. Illustratively, in one case, the first access network device is an LTE base station, and the second access network device is an NR base station, where the first network standard is LTE and the second network standard is NR. In another case, the first access network device is an NR base station, and the second access network device is an LTE base station, where the first network system is NR and the second network system is LTE.
The LTE base station may have one cell (i.e., only the PCell is included in the MCG) or may have a plurality of cells (i.e., the PCell and at least one SCell are included in the MCG). Similarly, the NR base station may have one cell (i.e., only PSCell is included in SCG) or may have a plurality of cells (i.e., PSCell and at least one SCell are included in SCG).
902. And the terminal performs ANR measurement on the neighboring cell according to the frequency band combination which is satisfied by the first frequency band and the at least one second frequency band (marked as X second frequency bands, wherein X is an integer greater than 0).
The terminal may obtain a carrier (i.e., a first carrier) of the neighboring cell through cell search. The ANR measurement mode adopted by the terminal may be idle period or autonomous gap.
It should be noted that, when data transmission is performed simultaneously between frequency bands satisfying the frequency band combination relationship, interference does not occur between the frequency bands.
The first frequency band is a frequency band to which the first carrier belongs, the first carrier is a carrier of a neighboring cell, and a network standard adopted by the neighboring cell is a first network standard. And when the first network standard is LTE, the adjacent cell is an LTE adjacent cell, and when the first network standard is NR, the adjacent cell is an NR adjacent cell.
The X second frequency bands are frequency bands to which at least one second carrier (denoted as X 'second carriers, where X' is an integer greater than 0) belongs, and the second carrier is a carrier of a cell of the second access network device that provides a service for the terminal, for example, when the second access network device is an NR base station, the second carrier is a carrier of a cell in an SCG, and when the second access network device is an LTE base station, the second carrier is a carrier of a cell in an MCG. Illustratively, when a cell of the second access network device that provides service for a terminal includes 4 cells, which are cell 1 to cell 4, respectively, second carriers corresponding to the 4 cells are second carriers 1 to second carriers 4, respectively, and frequency bands to which the second carriers 1 to the second carriers 4 belong, that is, X second frequency bands. The different second carriers may belong to the same second frequency band or may belong to different second frequency bands. When different second carriers belong to different second frequency bands, the correspondence between the cell, the second carrier, and the second frequency band can be seen in table 1.
TABLE 1
Figure PCTCN2020099598-APPB-000001
Optionally, the method further includes: and the terminal determines the frequency band combination which is satisfied by the first frequency band and the X second frequency bands in the first subframe. The first subframe is a starting subframe of an inactive time of the terminal for the first access network device (ANR measurement mode for idle period), or a next subframe of the first subframe is a reception window of MIB and/or SIB1 of a neighboring cell (ANR measurement mode for autonomous gap).
When determining the frequency band combination satisfied by the first frequency band and the X second frequency bands, the terminal may determine in a traversal manner. Specifically, before determining the frequency band combinations that the first frequency band and the X second frequency bands satisfy, the memory stores radio frequency parameters of the first frequency band and the X second frequency bands, and the NV stores radio frequency parameters of each frequency band combination. The terminal may compare (e.g., perform correlation calculation) the radio frequency parameters stored in the memory with the radio frequency parameters of each frequency band combination stored in the NV, and if the radio frequency parameters stored in the memory are found to be similar or identical to the radio frequency parameters of a certain frequency band combination stored in the NV, it indicates that a frequency band combination including the first frequency band and the X second frequency bands exists, otherwise, it indicates that a frequency band combination including the first frequency band and the X second frequency bands does not exist. Then, the terminal may deactivate a second frequency band (denoted as a second frequency band a) in the memory, that is, the terminal may cover the existing radio frequency parameters in the memory by using the first frequency band and X-1 second frequency bands (frequency bands other than the second frequency band a in the X second frequency bands), or, after deleting the radio frequency parameters of the second frequency band a in the memory, compare the radio frequency parameters in the memory with the radio frequency parameters of each frequency band combination stored in the NV, and find that the radio frequency parameters in the memory are similar or identical to the radio frequency parameters of a certain frequency band combination stored in the NV, which indicates that there is a frequency band combination including the first frequency band and the X-1 second frequency bands.
It should be noted that, when determining the frequency band combination, the terminal may not determine all frequency band combinations, but only determine the frequency band combination including the frequency band number greater than a certain threshold and/or the frequency band combination including the frequency band to which the carrier of the PSCell belongs, which is not limited in this application.
When performing an ANR measurement in the prior art, in order to avoid interference of communication of a terminal on a cell of a second access network device, which serves the terminal, with the ANR measurement of a neighboring cell, the communication of the terminal on the cell of the second access network device, which serves the terminal, is disconnected, thereby causing flow interruption. According to the method provided by the embodiment of the application, because mutual interference cannot be generated when data transmission is simultaneously performed between the frequency bands meeting the frequency band combination relationship, the terminal performs ANR measurement on the neighboring cell according to the frequency band combination met by the first frequency band and the X second frequency bands, whether the terminal disconnects communication on the cell, serving the terminal, of the second access network device can be selected according to needs, and flow interruption can be reduced. In addition, the terminal does not need to start the ANR measurement after the terminal enters the NR CDRX inactivity time, so that the problems that the LTE ANR measurement or the NR ANR measurement in scheme 2 cannot be started for a long time, the ANR measurement scheduling is delayed, the neighbor discovery is not in time, the accuracy of the network-side-initiated handover is low, and the like can be avoided.
The frequency band combination relationship that the first frequency band and the X second frequency bands satisfy may be in the following three cases (denoted as case 1, case 2, and case 3), and the implementation process of step 902 in the following three cases and three cases is described below.
In case 1, the first frequency band and the X second frequency bands constitute at least one frequency band combination, and a frequency band combination including the first frequency band and the X second frequency bands exists in the at least one frequency band combination.
In case 1, the step 902 may include, when implemented: and the terminal performs ANR measurement on the neighbor cell.
In case 1, a frequency band combination including a first frequency band and X second frequency bands may be referred to as a first frequency band combination. When the at least one frequency band combination includes the first frequency band combination, it is described that communication of the terminal on the cell of the second access network device, which provides service for the terminal, does not generate interference to ANR measurement of the neighboring cell, so that the terminal can directly perform ANR measurement on the neighboring cell without disconnecting communication of the terminal on the cell of the second access network device, which provides service for the terminal, and flow interruption is avoided.
Exemplarily, when the X second bands are 4 second bands shown in table 1, the first band and the X second bands form 5 band combinations, and the 5 band combinations can be referred to in table 2, and since the band combination 1 includes the first band and the 4 second bands shown in table 1, the terminal can directly perform ANR measurement on the neighboring cell.
TABLE 2
Frequency band combination Frequency band in a frequency band combination
Frequency band combination 1 A first frequency band, a second frequency band 1, a second frequency band 2, a second frequency band 3, a second frequency band 4
Frequency band combination 2 First frequency band and second frequency band 1
Frequency band combination 3 A first frequency band, a second frequency band 1, a second frequency band 2, a second frequency band 3
Frequency band combination 4 A first frequency band, a second frequency band 1, a second frequency band 3, a second frequency band 4
Frequency band combination 5 A first frequency band, a second frequency band 1, a second frequency band 2, a second frequency band 4
Case 2, the first frequency band and the X second frequency bands constitute at least one frequency band combination, and there is no frequency band combination including the first frequency band and the X second frequency bands in the at least one frequency band combination.
In case 2, the step 902 may include, when implemented: the terminal informs the second access network equipment to cut off the communication of the terminal on the N cells, and the terminal performs ANR measurement on the adjacent cells; the N cells are cells corresponding to N second carriers, the N second carriers are second carriers corresponding to second frequency bands not belonging to the first frequency band combination, the first frequency band combination is one of at least one frequency band combination, and N is an integer greater than 0.
When the N second carriers are second carriers that do not belong to the second frequency band corresponding to the second frequency band in the first frequency band combination, it is described that communication of the terminal on N cells corresponding to the N second carriers interferes with ANR measurement of the neighboring cell, and therefore, after the terminal disconnects communication of the terminal on the N cells, the terminal performs ANR measurement on the neighboring cell without disconnecting communication of the terminal on all cells of the second access network device that provide services for the terminal, thereby reducing flow interruption.
Illustratively, when the X second frequency bands are 4 second frequency bands shown in table 1, the first frequency band and the X second frequency bands form 4 frequency band combinations, where the 4 frequency band combinations can be referred to as table 3, and when the first frequency band combination is the frequency band combination 2, the terminal notifies the second access network device to disconnect the communication of the terminal on the cell 4 corresponding to the second carrier 4 corresponding to the second frequency band 4.
TABLE 3
Frequency band combination Frequency band in a frequency band combination
Frequency band combination 1 First frequency band and second frequency band 1
Frequency band combination 2 A first frequency band, a second frequency band 1, a second frequency band 2, a second frequency band 3
Frequency band combination 3 A first frequency band, a second frequency band 1, a second frequency band 3, a second frequency band 4
Frequency band combination 4 A first frequency band, a second frequency band 1, a second frequency band 2, a second frequency band 4
In case 2, the first frequency band combination may be any one of the frequency band combinations, and in order to reduce the influence on the traffic of the terminal, optionally, the first frequency band combination is an optimal frequency band combination in the at least one frequency band combination, where the optimal frequency band combination refers to the frequency band combination having the smallest influence on the traffic of the terminal after the communication between the terminal and the cell corresponding to the second carrier corresponding to the second frequency band not belonging to the frequency band combination is disconnected.
The influence of one carrier on the traffic of the terminal may be determined by parameters corresponding to the carriers, where the parameters may include one or more of the following: a bandwidth of an active part (BWP), a number of receiving antennas, and a latest Modulation and Coding Scheme (MCS). The smaller the parameter corresponding to the carrier is, the smaller the influence on the traffic of the terminal is. When the parameter corresponding to one carrier includes a plurality of parameters, the traffic influence on the terminal may be represented by a product of values of the plurality of parameters, and a smaller product indicates a smaller traffic influence on the terminal.
In case 1 and case 2, optionally, when the second access network device is an NR base station, the first frequency band combination includes a frequency band to which a carrier of a PSCell in an SCG of the second access network device belongs, and when the second access network device is an LTE base station, the first frequency band combination includes a frequency band to which a carrier of a PCell in an MCG of the second access network device belongs.
In case 3, the first frequency band and any one of the X second frequency bands do not form a frequency band combination.
In case 3, the step 902 may include, when implemented: and the terminal informs the second access network equipment to disconnect the communication between the terminal and the cells corresponding to the X' second carriers, and the terminal performs ANR measurement on the neighboring cells.
When the first band and any one of the X second bands do not form a band combination, it indicates that communication of the terminal on the X' second carriers generates interference to ANR measurement of the neighboring cell, and therefore, the terminal may disconnect all cells of the second access network device that provide services for the terminal, and then perform ANR measurement on the neighboring cell, so as to smoothly complete ANR measurement of the neighboring cell.
In the foregoing cases 1 and 2, optionally, before the terminal performs the ANR measurement on the neighboring cell, the method further includes:
11) the terminal notifies the second access network device to suspend the communication of the terminal on the M cells, and loads the radio frequency parameters (i.e., the radio frequency NV in the foregoing) corresponding to each frequency band in the first frequency band combination. By loading the radio frequency parameters corresponding to each frequency band in the first frequency band combination, the terminal can subsequently communicate on the cell through the new radio frequency parameters.
The M cells are cells corresponding to M second carriers, the M second carriers are second carriers corresponding to a second frequency band in the first frequency band combination, and M is an integer greater than 0.
In the foregoing cases 1 and 2, optionally, before the terminal performs the ANR measurement on the neighboring cell, the method further includes:
12) and the terminal opens the radio frequency front end paths of the first carrier and the M second carriers. The radio frequency front end access of the first carrier and the M second carriers is opened, so that the terminal can smoothly receive and transmit data.
In the foregoing cases 1 and 2, optionally, before the terminal performs the ANR measurement on the neighboring cell, the method further includes:
13) and when the loading of the radio frequency parameters corresponding to each frequency band in the first frequency band combination is completed, the terminal informs the second access network equipment to recover the communication of the terminal on the M cells. By restoring the communication of the terminal on the M cells, the terminal can normally communicate on the M cells during the ANR measurement of the neighbor cell, and the flow interruption is reduced.
Optionally, after the terminal completes the ANR measurement of the neighboring cell, for the second access network device, the method further includes:
21) and when the terminal is positioned in the activation time, the terminal informs the second access network equipment to suspend the communication of the terminal on the M cells and loads the radio frequency parameters corresponding to the X second frequency bands, and when the terminal is positioned in the deactivation time, the terminal directly loads the radio frequency parameters corresponding to the X second frequency bands. Optionally, when the loading of the radio frequency parameters corresponding to the X second frequency bands is completed, the terminal notifies the second access network device to resume the communication of the terminal on the cells corresponding to the X' second carriers.
After the terminal completes the ANR measurement of the neighboring cell, it needs to recover the communication of the terminal on the cell of the second access network device that provides service for the terminal, and therefore, the radio frequency parameters corresponding to the X second frequency bands need to be loaded. It can be understood that, for the second access network device, when the terminal is located within the activation time, the terminal needs to communicate on M cells, and therefore, in order to prevent loading of the radio frequency parameters corresponding to the X second frequency bands from being mistaken, communication of the terminal on the M cells may be suspended. When the terminal is located in the inactive time, the terminal does not need to communicate in M cells, and therefore, the radio frequency parameters corresponding to the X second frequency bands can be directly loaded.
Optionally, after the terminal completes the ANR measurement of the neighboring cell, the method further includes:
22) and the terminal loads radio frequency parameters corresponding to the S frequency bands. The S frequency bands are frequency bands to which carriers of a cell of the first access network device that provides service for the terminal belong. Optionally, when the loading of the radio frequency parameters corresponding to the S frequency bands is completed, the terminal notifies the first access network device to resume the communication of the terminal on the cell of the first access network device providing the service for the terminal.
After the terminal completes the ANR measurement of the neighboring cell, it needs to recover the communication of the terminal on the cell of the first access network device that provides service for the terminal, and since the communication of the terminal on the cell of the first access network device that provides service for the terminal is disconnected, the terminal may directly load the radio frequency parameters corresponding to the S frequency bands.
Optionally, after the terminal completes the ANR measurement of the neighboring cell, for the second access network device, when the terminal is located within the activation time, the method further includes:
31) the terminal opens the radio frequency front end paths of X' second carriers.
After the terminal completes ANR measurement of the neighboring cell, for the second access network device, when the terminal is located within the activation time, the terminal needs to communicate on a cell of the second access network device that provides service for the terminal, and therefore, the terminal needs to open radio frequency front end paths of X' second carriers.
Optionally, for the first access network device, when the terminal is located within the activation time, the method further includes:

In order to make the above embodiments more clear, the flow of the method provided by the present application is briefly described in the sequence from front to back in time series. Specifically, the following examples 1 to 3 are described separately.
Example 1
In embodiment 1, a case where the first access network device is an LTE base station, the second access network device is an NR base station, and a frequency combination relationship that the first frequency band and the X second frequency bands satisfy is the case 1 (that is, the first frequency band and the X second frequency bands form at least one frequency combination, and a frequency combination including the first frequency band and the X second frequency bands exists in the at least one frequency combination), and an ANR measurement manner is idle period is taken as an example to briefly introduce the flow of the method provided in this application.
Referring to fig. 11, embodiment 1 provides a method including:
1101. the terminal enters LTE CDRX non-activation time in a subframe 0, the terminal judges that ANR measurement needs to be started in the subframe 0, and the first frequency range and the X second frequency ranges form a frequency range combination.
In embodiment 1, the first frequency band is a frequency band to which a first carrier of an LTE neighboring cell belongs. The X second frequency bands are frequency bands to which carriers of all cells in the SCG belong.
1102. When the terminal is in a connected state with the NR base station, the terminal informs the NR base station to suspend the communication of the terminal on all cells in the SCG.
1103. And the terminal loads the radio frequency parameters of the first frequency band and the X second frequency bands and opens radio frequency front-end channels of the first carrier and carriers of all cells in the SCG.
1104. If the radio frequency parameters of the first frequency band and the X second frequency bands are loaded and the radio frequency front-end paths of the first carrier and the carriers of all cells in the SCG are opened in subframe 1 of the LTE CDRX inactivity time, the terminal resumes communication on all cells in the SCG and starts LTE ANR measurement.
During the measurement of the LTE ANR, the communication of the terminal on all cells in the SCG is performed normally, and when the terminal enters the NR CDRX inactivity time, the processing is performed according to a normal flow, so that the LTE ANR measurement is not affected.
1105. And in a subframe N +1 of the LTE CDRX non-activation time, the terminal completes LTE ANR measurement.
1106. When the terminal is in the NR CDRX activation time, the terminal informs the NR base station to suspend the communication of the terminal on all cells in the SCG, loads the radio frequency parameters of all cells in the MCG and the radio frequency parameters of all cells in the SCG, and opens the radio frequency front end channels of the carriers of all cells in the SCG.
1107. In subframe N +2 of the LTE CDRX inactivity time, the radio frequency parameters of all cells in the MCG and the radio frequency parameters of all cells in the SCG are loaded completely, and the radio frequency front end paths of carriers of all cells in the SCG are opened, and the terminal notifies the NR base station to resume communication on all cells in the SCG.
For example, referring to fig. 12, when the terminal does not perform ANR measurement, the terminal employs a radio frequency front end path 1, a radio frequency front end path 2, and a radio frequency front end path 3 to communicate on an NR cell 1, an NR cell 2, and an NR cell 3, respectively, where the NR cell 1 is a main secondary cell, and the NR cell 2 and the NR cell 3 are a secondary cell 1 and a secondary cell 2, respectively. When the terminal performs ANR measurement under the condition that the first frequency band and the X second frequency bands form a frequency band combination, the radio frequency front end path 1, the radio frequency front end path 2, and the radio frequency front end path 3 are respectively used for communicating on the NR cell 1, the NR cell 2, and the NR cell 3, and the radio frequency front end path 4 is also used for communicating on an LTE neighboring cell.

When the first access network device is an NR base station, the frequency band combination relationship that the second access network device is an LTE base station, the first frequency band and the X second frequency bands satisfy is the above case 1, and the ANR measurement mode is idle period, an implementation process of the method provided by the present application is similar to the process shown in fig. 11, which can be understood by reference and is not described again.
Example 2

Referring to fig. 13, embodiment 2 provides a method including:
1301. and the terminal judges that the subframe 1 is a receiving window of the MIB and/or SIB1 of the neighboring cell in the subframe 0, determines to start ANR measurement, and judges that the first frequency band and the X second frequency bands form a frequency band combination.
In embodiment 2, the first frequency band is a frequency band to which a first carrier of an LTE neighboring cell belongs. The X second frequency bands are frequency bands to which carriers of all cells in the SCG belong.
1302. The same as step 1102.
1303. The same as in step 1103.
1304. If the loading of the radio frequency parameters of the first frequency band and the X second frequency bands is completed in the subframe 1, and the radio frequency front-end paths of the first carrier and the carriers of all the cells in the SCG are opened, the terminal resumes the communication on all the cells in the SCG, and starts the LTE ANR measurement.
During the measurement of the LTE ANR, the communication of the terminal on all cells in the SCG is performed normally, and when the terminal enters the NR CDRX inactivity time, the processing is performed according to a normal flow, so that the LTE ANR measurement is not affected.
1305. And in the subframe N +1, the terminal completes LTE ANR measurement.
1306. As in step 1106.
1307. In subframe N +2, the radio frequency parameters of all cells in the MCG and the radio frequency parameters of all cells in the SCG are loaded completely, and the radio frequency front end paths of the carriers of all cells in the SCG are opened, and the terminal notifies the NR base station to resume the communication on all cells in the SCG.
For example, in embodiment 2, when the terminal does not perform the ANR measurement and performs the ANR measurement, refer to fig. 12 for communication of the terminal, which is not described again. Similar to example 1, under example 2, a (N/N +2) fold increase in flow rate can be obtained.
Example 3
In embodiment 3, the first access network device is an LTE base station, the second access network device is an NR base station, a frequency combination relationship that the first frequency band and the X second frequency bands satisfy is the above case 2 (that is, the first frequency band and the X second frequency bands form at least one frequency combination, and there is no frequency combination including the first frequency band and the X second frequency bands in the at least one frequency combination), and an ANR measurement manner is idle period.
As shown in fig. 14, the method provided in embodiment 3 includes:
1401. the terminal enters LTE CDRX non-activation time in a subframe 0, the terminal judges that ANR measurement needs to be started in the subframe 0, determines frequency band combinations consisting of the first frequency band and X second frequency bands, and determines the first frequency band combination in the frequency band combinations.
In embodiment 3, the first frequency band is a frequency band to which a first carrier of an LTE neighboring cell belongs. The X second frequency bands are frequency bands to which carriers of all cells in the SCG belong.
For example, the frequency band combination of the first frequency band and the X second frequency bands may be as shown in table 3.
In step 1401, in a specific implementation, the first frequency band combination may be a frequency band combination with the largest number of frequency bands, including a frequency band to which a carrier of the PSCell belongs, and when there are a plurality of such frequency band combinations, a frequency band combination with the smallest influence on the traffic of the terminal is selected. When there are a plurality of frequency band combinations with the minimum influence on the traffic of the terminal, one of the frequency band combinations is arbitrarily selected as the first frequency band combination.
For example, when the frequency band combination composed of the first frequency band and the X second frequency bands is as shown in table 3, and the parameters corresponding to the respective second frequency bands are as shown in table 4, since the frequency band combination 2, the frequency band combination 3, and the frequency band combination 4 are the frequency band combination with the largest number of frequency bands including the frequency band to which the carrier of the PSCell belongs, the first frequency band combination may be determined among the frequency band combination 2, the frequency band combination 3, and the frequency band combination 4. The second carrier 2 has an influence on the traffic of the terminal of 40 × 2 × P — 80P, the second carrier 3 has an influence on the traffic of the terminal of 50 × 4 × P — 200P, and the second carrier 4 has an influence on the traffic of the terminal of 60 × 2 × P — 120P.

Exemplarily, when the frequency band combination composed of the first frequency band and the X second frequency bands is as shown in table 3, and the parameters corresponding to the respective second frequency bands are as shown in table 5. Since the frequency band combination 2, the frequency band combination 3, and the frequency band combination 4 are the frequency band combinations with the largest number of frequency bands including the frequency band to which the carrier of the PSCell belongs, the first frequency band combination can be determined among the frequency band combination 2, the frequency band combination 3, and the frequency band combination 4. The influence of the second carrier 2 on the traffic of the terminal is 40 × 2 × 12 — 960, the influence of the second carrier 3 on the traffic of the terminal is 40 × 2 × 13 — 1040, and the influence of the second carrier 4 on the traffic of the terminal is 40 × 2 × 5 — 400, and since the influence of the second carrier 4 on the traffic of the terminal is the smallest, it is possible to determine that the band combination (i.e., the band combination 2) that does not include the second band 4 to which the second carrier 4 belongs is the first band combination.

Figure PCTCN2020099598-APPB-000003
1402. When the terminal is in a connected state with the NR base station, the terminal informs the NR base station to disconnect the communication of the terminal on the N cells, and informs the NR base station to suspend the communication of the terminal on the M cells.
The N cells are cells corresponding to the N second carriers, and the N second carriers are second carriers corresponding to second frequency bands not belonging to the first frequency band combination. The M cells are cells corresponding to the M second carriers, and the M second carriers are second carriers corresponding to the second frequency bands in the first frequency band combination.
1403. And the terminal loads the radio frequency parameters of each frequency band in the combination of the first frequency band and opens radio frequency front-end channels of the first carrier and the M second carriers.
1404. If the radio frequency parameter loading of each frequency band in the combination of the first frequency band and the first frequency band is completed in subframe 1 of the LTE CDRX inactivity time, and the radio frequency front-end paths of the first carrier and the M second carriers are opened, the terminal resumes communication in the M cells, and starts LTE ANR measurement.
During LTE ANR measurement, communication of the terminal on the M cells is normally carried out, when the terminal enters NR CDRX non-activation time, processing is carried out according to a normal flow, and LTE ANR measurement is not influenced.
1405. And in a subframe N +1 of the LTE CDRX non-activation time, the terminal completes LTE ANR measurement.
1406. When the terminal is in the NR CDRX activation time, the terminal informs the NR base station to suspend the communication of the terminal on the M cells, loads the radio frequency parameters of all the cells in the MCG and the radio frequency parameters of all the cells in the SCG, and opens the radio frequency front end channels of the carriers of all the cells in the SCG.
1407. In subframe N +2 of the LTE CDRX inactivity time, the radio frequency parameters of all cells in the MCG and the radio frequency parameters of all cells in the SCG are loaded completely, and the radio frequency front end paths of carriers of all cells in the SCG are opened, and the terminal notifies the NR base station to resume communication on all cells in the SCG.
For example, referring to fig. 15, when the terminal does not perform ANR measurement, the terminal employs a radio frequency front end path 1, a radio frequency front end path 2, and a radio frequency front end path 3 to communicate on an NR cell 1, an NR cell 2, and an NR cell 3, respectively, where the NR cell 1 is a main secondary cell, and the NR cell 2 and the NR cell 3 are a secondary cell 1 and a secondary cell 2, respectively. If the first frequency band combination does not include the frequency band to which the carrier of the NR cell 3 belongs, when the terminal performs ANR measurement, the radio frequency front end path 1 and the radio frequency front end path 2 are used to communicate with the NR cell 1 and the NR cell 2, respectively, and the radio frequency front end path 3 is used to communicate with the LTE neighboring cell.
In embodiment 3, it is assumed that the NR base station has K service carriers and the service traffic of each service carrier is average, and the PDSCH scheduling of each time slot is uniform, if the communication of the terminal on the cell corresponding to the partial carrier is interrupted, L service carriers (L < K, and L service carriers include the carrier of the PScell) remain, the service continuity of the NR remaining service carriers of N LTE subframes can be ensured in N +2 LTE subframes, and the traffic can be improved by (L/K) ((N/N + 2)) times.
When the first access network device is an NR base station, the frequency band combination relationship that the second access network device is an LTE base station, the first frequency band and the X second frequency bands satisfy is case 2, and the ANR measurement mode is idle period, an implementation process of the method provided by the present application is similar to the process shown in fig. 14, which can be understood by reference and is not described again.
